StarCrack AI http://darkblizz.org/Forum2/ai-scripts/starcrack-ai-official-thread/
StarCrack AI has been in development since the first AI hack was on the scene. Initially, it was a pretty hacked up version of the Blizzard "very easy" AI that would actually do more than build two marines that glare at you. Since then it has evolved into one of the leading AIs for StarCraft 2.
Latest Version: 5.5
V5.5 Changelog:
- Multiple opens for each race.
- Zerg and Terran opens have been re-written.
- AI has a delay before he scouts.
- AI should attack in larger waves and more often.
- Lots of balancing and tweaking!
